Abstract:In this paper, Biogeography Based Optimization (BBO) algorithm is used to improve voltage profile of the distribution networks considering cable aging constraint and optimal siting and sizing of DSTATCOMs. Recently, researchers show the importance of cable aging effects in the planning of power systems. Cable aging mostly happens due to metallic structure of power equipment such as cable sheathing erosion. Decreasing reliability of the system and higher risk of failure are some results of cable aging. In order to overcome this issue in power system, one of the best methods is the reduction of cable current flow by installing Flexible Alternating Current Transmission System (FACTS) devices. FACTS devices can help to overcome the hazards that happen in the operation stage of power systems. In this regard, Distributed Static Compensator (DSTATCOM) is used here. The IEEE 33-bus standard network is used in our experimental studies as the test system and load flow calculations are carried out by Backward/Forward sweep method in this work. Three scenarios are investigated in the simulation and the BBO algorithm is used to find optimal sites and sizes for each scenario. The results obtained from BBO, show the privilege of the proposed method.

This paper presents optimal placement of Static Series Voltage Regulator (SSVR), for voltage profile improvement and power loss reduction in radial distribution systems under steady state condition. SSVR consists of a series compensator. The series compensator injects the series voltage in quadrature with the branch current in such a way that the receiving end voltage is maintained at desired value (up to 1 p.u). The criteria for selection of optimum location of SSVR are under voltage problem mitigation and loss reduction in the network under steady sate condition. Particle Swam Optimization (PSO) technique is used to find the rating of the device. The proposed model is tested using standard distribution system consisting of 33 nodes.
